It's a tangential relationship and a tiny point, but not convoluted. Luther's attitude toward Jews was part and parcel of Europe's ancient, widespread and deeply ingrained anti-semitism, of which Krystallnacht was a drastic expression.
I think Luther’s antipathy toward the Pope and Papacy and his actions resulting from both are of much greater historical significance than his beliefs about Jews. Europe was anti semitic before Marty came along.
